4 Claims. (Cl. 81--19) The present invention relates to improvements ina vise for supporting pipe during caulking. It consists of thecombinations, constructions, and arrangement of parts as hereinafterdescribed and claimed.

It is a well-known fact that each section of sewer or soil pipe isprovided with an enlarged bell-shaped portion at one end thereof, intowhich an end of an adjacent section of pipe may be inserted to provide ajoint. This joint is caulked by first pressing oakum, or other suitablecaulking material, into the bell-shaped portion, and then pouring leadinto the bell to complete a water-tight joint.

As the cardinal object of our invention, we provide a vise that isarranged to support a section of sewer pipe in vertical position withthe hell-shaped portion projecting upwardly. Thereafter, a secondsection may be inserted into the rst, and the joint readily caulked bythe plumber.

More specically described, We provide a vise that is adapted to beVsecured to a Work bench so that its jaws will project beyond an edge ofthe bench. The projecting ends of the jaws have coacting saddlesthereon, which are disposed to be positioned on opposite sides of avertically-arranged sewer pipe. One of the jaws is movable relative tothe other so as to grip the pipe therebev tween.

Another object is to provide a vise of the character described, which isdesigned in such a manner as to grip pipes that vary in exteriordiameters from standard sizes.

Other objects and advantages will appear as the specification continues,and the novel features will be pointed out in the claims hereuntovappended.

y DRAWING For a better understanding of our invention, reference shouldbe had to the accompanying drawing, forming part of this specification,in which:

Figure l is a top plan view of our vise, illustrating it as beingmounted on a fragmentary portion of a work bench;

Figure 2 is a longitudinal multiplane sectional view taken along theline 2-2 of Figure 1; and

Figure 3 is a fragmentary elevation, the superstructure appearing as atransverse sectional View, as seen from the plane 3-3 of Figure 1.

While we have shown only the preferred form of our invention, it shouldbe understood that Various changes, or modifications, may be made withinthe scope of the annexed claims without departing from the functionthereof.

Detailed description Referring now to the drawings, it will be notedthat we have provided a vise having xed and movable jaws A and B,respectively, which are mounted on a work bench C so as'to projecthorizontally beyond an edge 10 of the latter. For the purpose ofmounting these jaws, a base member D is fastened to the edge portion ofthe bench, and an anchor bar E is fastened to the bench inwardly fromthe edge 10.

As vclearly shown in Figures 1 and 2, the base member D is fashionedfrom angle iron, with the vertical and horizontal flanges 11 and 12being butted against the edge 10 and the top 14, respectively, of thework bench. Lag screws 15, or other suitable fastening means, may beutilized for securing the base member to the work bench. Likewise, theanchor bar has been disclosed as being fastened by lag screws 16 (orbolts) to the top 14 of the bench. The anchor bar E has been illustratedas being mounted in parallel relation with the base member D.

With respect to the fixed jaw A, its inner end 17 is rigidly secured tothe anchor bar E, its intermediate portion 18 is fastened to the basemember D, and its outer end 19 projects beyond the edge 10 of the workbench. Regarding the movable jaw B, its inner end 20 is pivotallyattached by a pin 21 to the anchor bar E, its intermediate portion 22 isslidably guided by the base member D, and its outer end 23 projectsbeyond the bench edge 10.

Moreover, the base member D is provided with an upstanding flange 24,which is fashioned with a horizontallydisposed slot 25. The intermediateportion 22 of the movable jaw B extends through and is guided in itsmovement by the walls of this slot.

It will be observed that the projecting ends 19 and 23 of the jaws areprovided with coacting saddles 26 thereon, which have gripping surfaces27 disposed in confronting relation with one another so as to bepositioned on opposite sides of a vertically-arranged sewer or soil pipeF interposed between the saddles. As shown, the saddles dene sections ofcylinders. Each of these sections has vinner and outer lateral ends 28and 29, respectively, the

former being disposed closer together than the latter. This arrangementwill permit the pipe F to be inserted into the saddles between the outerends 29, when the movable jaw is swung into the dot-dash line portionshown in Figure 1, while the inner ends 28 will serve to limit movementof the pipe towards the base member D.

For the purpose of operating the jaws, we have provided a jaw-actuatingmechanism designated generally at G. In its structural features, thismechanism includes a lever handle 30, which has one end thereofswingably attached by a pivot pin 31 to a bracket 32. The latter isprovided by a pair of lugs that are secured to the movable jaw B so asto move the latter. Also, a yoke 33 has one of its ends pivotallysecured by a journal pin- 34 to the lever handle 30 intermediate theends of the handle (see Figures l and 3). A rod 35 is connected to theother end of the yoke, and slidably extends through an aperture 36fashioned in a flange 37. This ange is rigidly attached to the fixed jawA.

It will be noted from Figures l and 3 that the rod 35 has its outer endprojecting beyond the flange 37. At least one nut 38, and preferablytwo, are adjustably threaded on the projecting end of the rod 35.Moreover, a spring 39 encircles the rod, and is interposed between theange 37 and the nut or nuts 38.

When the lever handle 30 is swung in one direction about its journal pin31 for clamping the pipe F between the jaws, that is, into the positionshown in Figure 3, the handle and the yoke 33 will constitute aself-locking toggle. However, upon swinging the handle 3l) in theopposite direction, as suggested by the arrow 40, the toggle will beunlocked; and, at the same time, a stop 41 on the rod 35 will abut theflange 37. As the plumber continues to move the handle 30 in thedirection of the arrow 40, the movable jaw B will be moved away from thefixed jaw A, thus releasing the grip of the jaws on the pipe F.

It will be appreciated, of course, that the exterior diameters of thepipe sections will vary from standard sizes.

3 Accordingly, the spring 39 has been provided so that it will yield,when the jaw B is brought up against the pipe F, and it is necessary tomove the handle 30still farther in ordert'o iockthe toggle. ylt is quiteobviousthatthe lengths of the jawsA'andB may be modied'soithat visesmaybe provided that will'a'ccominodateepipesof diierent diameters.

Sumiitary of operation Assuming that our vise jaws A and l B are mountedon the work bench C so as tofproject lbeyond the edge of the latter,'asillustrated in Figures 1 and 2, the operation of thevise is summarizedbriefly as follows:

As the Vfirst step, the plumber should swing the lever handle in thedirection ofthev arrow 40 (see Figure 3), therebyswinging the movablejaw B intro the dot-dash line position shown in Figure 1 At vthis time,the outer lateral ends 29 ofthe coacting saddles 26fwill be spaced asuicient distance to permit the section F of sewer or s oil pipe to beinserted therebetween, with its bell-shaped portion 42 facing upwardly(see Figure 2).

Subsequently, the lever handle 30 should be swung yinto the full-lineposition, asshown in Figures land 3, with the gripping surfaces 27 ofthe saddles 26 firmly engaging with the pipe section As willbe apparentfrom Figure 3, the lever handle 30 and the yoke 33 will constitute alocked toggle at this time.

Now the plumber may insert the lower end 43 of a second section F2 ofsewer or soil pipe into the bell-shaped portion 42 ofthe rst section. Infollowing the usual practice of caulking joints, an annular layer/i4 ofoakurn, or other caulking material, should be inserted into thebellshaped portion 42 so as to surround the lower end 43 of the secondsection of pipe. When vthis has been accomplished, a layer of moltenlead 45 should be added above the oakum, thus completing the caulkedjoint when the lead hardens.

Upon swinging the lever handle 30 in the direction of the arrow (seeFigure 3), the movable jaw B will be swung away from the fixed jaw A,thus releasing the grip of the saddles 26 on the pipe section F. Thiswill permit the caulked sections of the sewer or soil pipe to be removedfrom the vise.
